Wheel Bolt Pattern Tool
I've spent most of my life scrounging around salvage yards and swap meets searching for the latest and greatest of treasures. When looking through a pile of wheels or stack of rear axles, one of the most difficult things to do is find out what the wheel bolt pattern is. Trying to use a tape measure can be difficult to get into tight places, especially around hubs, and can be hard to read. Well, Speedway Motors has just the tool to make this task as easy as pie with the Wheel Bolt Pattern Tool, part number 910-60021.
This wheel bolt pattern tool will measure the bolt patterns on 4-Lug, 5-Lug, 6-Lug, and 8-Lugs wheels, axles, and hubs. It will show measurements in inches as well as millimeters, and the numbers are easy to read. The wheel bolt pattern tool also has a diagram to show how to use it and is small enough to easily fit in a hand-carried toolbox, a coat, or back pocket.
The wheel bolt pattern tool couldn't be easier to use when needing to check the wheel bolt pattern on a wheel. The tool has two male pins that fit into the wheel lug openings, and the tips are tapered to accommodate different lug stud hole sizes on the wheel.
When using the tool, put the pin in any one of the lug stud holes in the wheel and slide the second pin down the scale. Then put the second pin into the next lug stud hole.
This is an old wheel off of my stock car and as you can see, it measures 4 3/4-inches or 120-mm. Some wheel companies are measuring the bolt patterns in millimeters, so this tool makes it very easy to tell what pattern you have whether it's standard or metric.
The bonus to the wheel bolt pattern tool is the ability to measure the bolt pattern of an axle or a hub. Directly across from the pins are two female bosses that can be slid onto a lug stud. Just as checking a wheel, the first boss is slid over a lug stud and the second one is slid over the next lug stud. Being able to measure an axle or hub like this eliminates the chance of getting an incorrect measurement trying to measure over the center hub.
To measure the wheel stud pattern on the rear axle of my Laguna S-3, I slipped out to the garage and slid the wheel bolt pattern tool over two of the wheel studs.
I remember buying a set of chrome reversed wheels for my first car, which was a 1963-1/2 Ford Galaxy 500 XL. The ad said "Chrome Reversed Wheel Fits Ford", After getting them home I realized they weren't 5 x 4-1/2” wheels for a car, but 5 x 5-1/2” wheels for a truck. Don't let that happen to you, pick up a wheel bolt pattern tool from Speedway Motors, and avoid the guess-work!
